RE: adding ailerons
chuck mary,
I have a JMD Models kit (now out of production) that has glass fuse and of course ailerons. I believe it is about 72" span. The plane is unbuilt at this point. The plane can be built with fully sheeted wings (simulates metal covered wings, which some planes have) or just built-up (simulates original standard fabric covered wings.)
I have had a Saito 60T twin that I bought just for this plane. This engine is as smooth as an electric motor.
If you want, I could post pictures of the plans to allow you to construct the ailerons in a scale manner. I believe the plane is very much to scale, as the owner of JMD Models owns a full scale Silvaire from which he drew the plans.
Regards,
Randy Little
